Clover plot is loaded with these. Not sure if it is a weed or what and if it is a week how to get it under control?
If you didn't plant some sort of brassica then it's a wild mustard. I don't worry about it in food plots. I'd rather have a few weeds than to have all the forage coated with chemical for deer to browse. If I was concerned over it I'd mow it off.
The ones in my plot have more stem to them but yes I had a turnip and brassica mix there last fall and frost seeded in some clover.
If you had a brassica mix than that is more than likely rape. Which from experience is a nasty plant to get rid of, mowing won't always do the trick. Also if it goes to seed ...wow!
